LDS3: Applying Digital Preservation Principals to Linked Data Systems

Data publishing using semantic web and linked data techniques enables the sharing of detailed information. Importantly this information is shared using common standards and vocabularies to enable simple re-use. In the digital preservation community, an increasing number of systems are adopting linked data techniques for sharing data, including the PRONOM and UDFR technical registries. In many systems, only current information is being shared. Further, this information is not being described with data relating to who and when it was published. Such basic metadata is seen as essential in all digital preservation systems, however has been overlooked to a large extent when publishing linked data. This failing is partly due to there being very few specifications, reference implementations and verification systems in place to aid with publishing this type of linked data. This publication introduces the Linked Data Simple Storage Specification, a solution that enables careful curation linked data by following a series of current best practise guidelines. Through construction of a reference implementation, this work introduces how historical information can be referenced and discovered in order to build customisable alerting services for risk management in preservation systems.
